SPECIFICATION forming part of Letters Patent o. 609,412, dated August 23, 1898.

Application led Feblllaly 11,

` To a/ZZ whom t may concern:

Be it known that 1, HENRY DAvIs COFFEY, a citizen of the United States, residing at Gays, in the county of Louisa and State of Virginia, have invented a new and useful Churn, of which the following is a specification.

The invention relates to improvements in churns.

The object of the present invention is to improve the construction of working-body churns and to provide a simple and inexpensive one capable of rapidly producing butter at the expenditure of a minimum amount of labor and adapted to be readily cleaned.

A further object of the invention is to provide a churn in which the churn-body can be conveniently removed from its supporting frame or stand and also from the means for holding it in such frame or stand, so that the churn-body may be stored away separately, if desired, when the churn is not in use.

The invention consists in the construction the same. Fig. 5 is a detail sectional view' showing one of the tapering lugs of the churnbody and the recess at one side of the band.

Like numerals of reference designate corresponding parts in all the figures of the drawings.

1 designates a ohurnbody journaled in a supporting frame or stand 2 by means of a band 3, which encircles the churn-body 1 at the center thereof and is detachably secured to the saine, so that the churn-body may be readily removed from it and from the stand to facilitate cleaning the body after the operation of churning has been completed and to enable the churn-body to be stored away sepa= rately from the stand and the band when the churn is not in use. The stand 2 is composed of vertical sides or standards 4, secured to 189s.` serrano. 669,921. oramai.)

bottom sills or pieces 5 and connected by a transverse bar 6, the bottom sill5 and the transverse bar 6 forming the base of the stand.

The standards 4 are provided at their upper ends with bearing-recesses '7,`Which detachably receive journals 8 and 9 of the ring or band 3, and the journal 8 carries a crankhandle 10, preferably formed integral with it, but which may be constructed in any other suitable manner. The journals and the ring or band are preferably formed integral with each other; but they may be otherwise constructed, if desired.

The churn-body 1, which is cylindrical or substantially-so,preferably consists of a stone jar; but a tapering wooden churn-body 11, such as is shown in Fig. 4 of the drawings, may be employed, and the' invention is applicable to various other shapes of churnbodies, as will be readilyunderstood.

The churn-body l is provided with a cen` tral exterior enlargement or rib 12, which may be `of the shape illustrated in Figs. land 2 of the accompanying drawings, but which may be formed'by aswell or other form of enlargement. The rib or enlargement 12 engages one edge of the band 3, forming a stop for the same, and the opposite edge 13 is engaged -by a pair of lugs 14, preferably formed integral with the stone churn-body, but adapted to beapplied .in any suitable manner, such as indicated in Fig. 4 of the drawings.

The lugs 14 are preferably tapering in horital section, as rshown in Fig. 5 of the drawings, in order to pass readilythrough pas sages or recesses l5 at opposite sides of the band to permit the latter to bearranged between the lugs 14 and the enlargement 12. The lower edge 13 of the band is oppositely tapered at each side of ,the same, as clearly illustratedin Figs. l and 4Jof the drawings, and by rotating the band or the churn-.body the cams formed by the'tapering portions of the band bind or Wedge themselvesbetween the lugs Vand the enlargement or rib 12, whereby the parts are tightly clamped together. By forming a double cam at each side of the band the latter or the churn-body may be rotated 4in either direction to clamp the parts. By detachably journaling the band in the recesses of the stand and removably mounting the churn-body on the band the IOG said body may be quickly detached from its supports to enable it to be readily cleaned Without inconvenience in handling other parts of the churn.

The churn-body is provided with a removable cover 16, which is fastened in place during the operation of churning by means of a bail 17 and a clamping-lever 18. The terminals of the bail may engage handles 19 of the churn-body 1, as shown in Fig. 1 of the drawings, or it may be permanently hinged to ears 20, as shown in Fig. 4, and when connected to the churn-body in this manner it is adapted to serve as a handle for carrying the receptacle. The clamping-lever, which is preferably constructed of a single piece of resilient material, consists of a U-shaped loop, having its terminals coiled around the transverse portion of the bail to form eyes 22 and extended beyond the eyes to provide arms 23 for engaging the lid or cover 16.

The loop and the arms, which engage the cover, clamp it tightly on the churn-body and are adapted to release it readily by swinging the loop to carry the arms out of engagement with the cover.

The invention has the following advantages: The churn, which is simple and exceedingly inexpensive in construction, is capable of rapidly producing butter by simply rotating the churn-body to cause the contents thereof to dash back and forth from one end of the same to the other end thereof, and the churn-body may be readily separated from the other parts of the churn, so that it can be conveniently and thoroughly cleaned. '[he supporting-band, which is detachably secured to the churn-body, is adapted to be engaged with the same by rotating it in either direction, and it is adapted to abut againsta projecting rib or enlargement or the natural taper of a receptacle.

Changes in the form, proportion, and minor details of construction may be resorted to Without departing from the spirit or sacric- I ing any of the advantages of this invention, such as providing means for rotating the churn-bod y by foot or other power instead of by hand. What I claim is 1. In a churn, the combination of a supporting frame or stand, a churn-body provided With a lug, and a band journaled on the supporting frame or stand and arranged on the exterior of the churn-body and interposed between the lug and an adjacent portion of the said body, said band having a passage for the lug and being tapered to provide a cam, whereby it is adapted to be rotated to clamp the body, substantially as described.

2. In a churn, the combination of a stand provided with bearings, a churn-body having an enlargement and provided at opposite sides with lugs, and a band encircling the churn-body, journaled in the bearings of the stand and provided at opposite sides with recesses to permit it to pass the lugs, said band being oppositely tapered to form cams and adapted to be rotated in either direction to engage the lugs and clamp the churn-body, 7o substantially as described.

3. In a churn, the combination of a stand, a churn-body provided with a rib extending around it, near its center, lugs arranged on the churn-body and spaced from the rib, and a band provided with journals and mounted on the stand, said band having passages for the lug and being tapered to form cams for engaging the lugs and the rib, substantially as described.

In testimony that I claim the foregoing as my own I have hereto afiiXed my signature in the presence of two Witnessess.

HENRY D. COFFEY.
